I'm running a pair of Dali Oberon On-Wall speakers with this. They're not cheap, so I wanted a quality amplifier that was going to do them justice, while not damaging them from on/off pops/thumps or under-power distortion. Thankfully this runs them effortlessly to very loud volumes with no audible distortion.
My second biggest concern was idle background hiss, which would be an issue in my 'always-on' use case. However I'm pleased to say there is very little of this. You'd need to have your ear right up to the driver to hear it, so while it could be quieter (i.e. silent), I'm satisfied in this regard.
The general quality of audio seems to be high. I noticed no obvious defects in frequency response. Bass has satisfying impact.
The auto-off feature is great one for my use case; though I don't see why it's set to 15 minutes, when it could easily have been 15 seconds. There is no on/off thump or pop whatsoever, so a more aggressive standby mode would have been welcome.
I've not needed to use the limiter, but it is a welcome feature.
What really surprised me was the high quality of the case, switchgear and power supply. All are top-notch and put some HiFi equipment to shame. The volume pot is rock solid with no wobble. The case is a lovely Matt black with a durable finish. The supplied mounting brackets are solid. The power supply is a quality EU unit and the UK adapter provided seems to be a decent one. The supplied plug-in speaker terminal makes connection easy.
I highly recommend this amplifier.
